FLUUH SAWING AND RABBETlNG MACHINE.

SPEGIFIOATTQN forming part of Letters Patent No. 667,978, dated February12, 1901.

Application filed August 21, 1900. Eerial No. 27,667. (No modeli) is itknown that we, FRANK B. GARDINER and WILLIAM H. K. ABBOTT, citizens ofthe United States, residing at Vaterville, in the conntyof Kennebec andState of Maine, have invented new and useful Improvements in FloorSawing and Rabbeting Machines, of which the following is aspecification.

Our invention relates to floor sawing and rabbeting machines; and theobject of the same is to provide simple and efficient mechanism forrepairing and resurfacing floors.

l'leretofore ithas been the common practice to remove old fioors or wornportions thereof by hand, and the tools ordinarily used for this purposeare the chisel and mallet. This process is not only slow and tedious,but expensive, owing to the fact that much time is consumed in theoperation of removing defective boards and resetting new ones where onlyrepairs are necessary, while the expense of reflooring or resurfacing isstill greater.

The object-of our invention is to providea mechanism to repair orresurface floors expeditiously, cheaply, and more perfectly than hasheretofore been done by hand.

With this object in view our-invention consists of the mechanismillustrated in the accompanying dra .rings, in which Figure 1 is a sideelevation of a machine made in accordance with our invention. Fig. 2 isa plan view of the same. Fig. 3 isa rear end elevation of the same.

Like numerals of reference designate like parts wherever they occur inthe different views.

Our machine is designed to be mounted upon a wheeled truck and movedalong the floor by any suitable power. For the purposes of thisspecification a hand-operated machine has been illustrated in thedrawings.

Suitably journaled in the framework 1 of the machine are the front andrear axles 2 3 of the carriage or truck of the machine, and upon theends of the axles are fitted the wheels 4 5 6, said wheels 4 beinggrooved in their peripheries and designed to run upon a track secured tothe floor to be repaired or resurfaced. The wheel 5 is provided with aseries of spurs 7, which engage the floor and serve to propel themachine. The wheel 6 may have a plain periphery, and the front axle 2,upon which this wheel is fitted, may be connected to the frame in amanner to have lateral swing or vibration. Keyed centrally to the rearaxle 3 is a beveled gear 8. A yoke 9 is mounted loosely upon the axle 3,and journaled at 10 in said yoke is a longitudinal shaft 11, having apinion 12 keyed thereto, said pinion meshing with the beveled gear 8.The opposite end of the shaft 11 is fitted with a spur-gear 13 in meshwith a Worm l4, keyed to a transverse shaft 15, journaled in the frame.This shaft 15 has keyed to it a large cog-wheel 16, which meshes with anidler 17, and the idler is in mesh with a gear-wheel 18 on thetool-shaft 19, journaled in hangers 20, depending from the idler-shaft21, to which the hangers are loosely pivoted. The shaft 19 has fitted toits outer end asaw 22, and it will be understood that a series of sawsmay be secured to said shaft, said saws being spaced apartv by rings orwashers. A grooving or rabbeting tool or a planing-tool may be securedto this shaft in place of the saw. Secured to the hangers 20 is agageplate 23, supported by the slotted link 24, pivoted at its lower endto the gage 23 and at its upper end to a link 24, connected at its upperend to an adjusting-lever 25. An arm 26 is pivoted at one end to thegage-plate, and its opposite end is pivoted to a traveling nut 27,fitted to a threaded rod 28, journaled longitudinally in the frame andprovided with a hand-wheel 29 for turning it. The lever consists of thearm 25, to which the link 24 is pivoted, the arm 25", pivoted to theframe of the machine, and the handle 25. The movement of this handleregulates the depth of cut of the tool mounted on the shaft 19 and therelative position of the gageplate 23.

Rising from one side of the frame is a standard 30, having journaled atits upper end a fly-wheel 31, having a crank or handle 32. A belt 33passes around the wheel 31 and around a pulley 34 on the shaft 15. Abelttightener, consisting of a pulley 35, journaled in a curved arm 36,pivoted at 37, may be used to insure contact of the belting.

Near the front end of the shaft 11, at the side of spur-wheel 13, is acollar 14, to which a yoke 14 is secured by set-screws 14. Dependingfrom the yoke 14 is a rod 14:, which slides in a tubular casing H saidtubular casing having two notches 14 therein. A dog 14 is pivoted to theyoke 14 and when it is desired to disconnect the spur-wheel 13 from theWorm 14 the shaft 11 is raised, carrying the dog 14 until the toe 14engages the upper notch 14 and throws out the sawoperating mechanism. Inorder that the saw 22 may be raised above the floor-surface to move themachine about without actuating said saw, the lever 25 may be throwntoward the left in Fig. 1 to lie in a horizontal plane.

The operation of our machine is as follows: An iron rail of the rightcontour to fit the grooves in the carriage-wheels 4 is secured to thefloor at the required distance from the board which it is desired toremove from the floor. The wheels t are placed upon the track and themachineis moved along on the floor, the spur-wheel 5 engaging the floor.The handle 25 is actuated to give the required depth of cut to the sawor other tool and the handle 32 is turned toactuate the tool. When it isdesired to form a groove or rabbet in the floor to set a new board, agroove or rabbet plane may be substituted for the saw, or asmoothing-plane may be used in place of the saw.

From the foregoing it will be obvious that operations of the characterreferred to may be carried on expeditiously and that a machine made inaccordance with our invention is capable of other uses in the art ofWoodworking.

Having thus fully described our invention, what we claim is 1. Aflooring machine mounted upon a wheeled carriage, two of the wheels ofsaid carriage being peripherally grooved to run upon a track, aspur-wheel designed to engage the surface over which the carriage is tobe moved, a tool-shaft journaled in hangers pivoted to the frame, meansfor actuating said shaft, a'tool mounted on the shaft, a gage fordetermining the depth of cut of the tool, and means for adjusting thetool shaft and gage, substantially as described.

2. In a flooring-machine, a wheeled carriage, a tool-shaft journaled inhangers on the carriage, a gage-plate connected to the hangers, a leverconnected to the gage-plate by a slotted link, an arm connected to thegageplate and to the link, and means for adjusting the armlongitudinally and the gage-plate and tool vertically, substantially asdescribed.

3. In a flooring-machine, a wheeled carriage, a standard risingtherefrom, a handwheel journaled to said standard, a tool-shaftjournaled to hangers pivoted to the carriage, the rear axle of thecarriage havingagrooved wheel at one end and a spur-wheel at the other,a beveled gear on said shaft, a longitudinal shaft having a pinion inmesh with said beveled gear, a spur-gear at the opposite end of saidlongitudinal shaft, a Worm in mesh with said spur-Wheel, said worm beingmounted on a transverse shaft, having a cogged wheel secured thereto andin mesh with an idler for transmitting power to the tool-shaft,substantially as described.

4. In a flooring-machine, the combination, substantially as described,with a carriage mounted on wheels, means for propelling the carriageover the floor, a tool-shaft journaled in hangers pivoted to the frame,a tool mounted on said shaft, means for revolving said shaft to actuatesaid tool, a gage for determining the depth of the cut of said tool, andmeans for adjusting the said shaft and said gage.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
